I’ve never personally run into the issue that you experienced and I haven’t heard about it before and other plywood boats have been built from this plan, so I’m not sure what the issue was. Feel free to send me pictures. It seems slightly odd that the length would be different, so there might be a printing issue. I’m just not sure.

For an increase in length, as long as everything stay proportional it should turn out fine. I’d actually suggestion switching to a cedar strip. The hull is easy to plank and goes quickly — perfect for a group project. One team works on the port and the other on the starboard.

Thanks,

The small group of men at our church have greatly enjoy working together to build the Iggy from scratch. A couple of us have made kits, but this was our first attempt at punching the plan on to the okoume and going from there.

We’ve got the deck just about stripped in (we’re doing a hybrid using the PDF files you sent for a plywood hull and cedar strips on the stations for the deck) and it should be a kayak pretty soon. I’ll send you photos.

We’ve had a couple issues I thought I would ask you about:
1. We had an issue in the stitch-n-glue hull at the bow. The upper strake, the shear, would not stand on the edge of the bottom hull strake without buckling the material (stitched from stern to bow). The shear line would no longer be fair. We resolved this by allowing the shear strake to overlap the bottom strake, in a relaxed position, and then drew a line at the overlap. We then sawed off a small piece at that line – at the bow tip of the bottom stake. We had to remove a slice of about 3/4″ high by about 4″ long. A triangular gap of about 1/2″ resulted in the keel, but we filled the keel with epoxy fillet (wood flour), anyway, and it looks fine. This is above the water line, so the shape of the boat in the water is not affected. Have you run into that before? Maybe we had a problem in the transfer of the plan…
2. The boat seems to be slightly shorter than the specs. Everything if fitting just fine, but it comes in at just a hair over 16′ in total length. That’s ok with us. It looks sweet. But we’ve got some bigger guys and in the future we might want to make an Iggy at about 17′ with a bit more beam (and displacement). How would we do that? Can we just enlarge the print percentage of the PDF file, e.g., print at 106% for both the strakes and stations? Seems like that would keep things in proportion.

This has been a great project to gather together some men of our church who needed the “fellowship.” Thanks!

I’d like to see a copy of the cedar deck in the 2.6 file format if you’ve got time to attach that to an email. Thanks! I’m glad I found your blog.

Tough questions. :)

I left the deck off the developable version because the deck I drew isn’t developable — it’s a deck designed for cedar strips — that’s what you’re seeing in the Igdlorssuit_FV_S_Deck_afterbuild.fbm file. That’s not an issue for you because you’re using a strip-built deck, but it makes it slightly more difficult for your friends who want to do all stitch-and-glue. For you, just use the deck from the pdf file after you print it. If you need a copy of the file with my cedar deck, email and I’ll send you a 2.6 file format version.

For your friends, consider a simple plywood radius deck. Chris Kulczycki describes the method in The New Kayak Shop: More Elegant Wooden Kayaks Anyone Can Build. It’s quick and the sheet of plywood for the deck is cut after the hull is completed. This method results in a classic-Anas-Acuta-style look.

Let me know if this works for you. If not, drop me an email and we can figure something out for your friends.

The files I downloaded from this page have the hull strakes in Free!Ship plans where I can print the hull panel developments, as well as the stations in a nice PDF. Thanks, Bryan, for the great work! There is, however, no deck on the Free!Ship plan.

A couple of guys from my church would like to do a first-time build together of the Iggy, all as stitch and glue. The file Igdlorssuit_FV_S_Deck_afterbuild.fbm has the deck strakes, too; but not in Free!Ship readable format. They are readable in the free version of DelftShip, but there is no way to export them or print them. I’m stuck ,unless I buy a full copy of DelftShip just to print the deck strakes.

Has anybody made a PDF or DXF of the Iggy deck stake developments?

Thanks!
